Studies have been carried out aimed at improving the corrosion resistance of concrete and its other characteristics for operation in harsh environmental conditions. The influence of a complex additive containing multilayer carbon nanotubes and hydrothermal SiO2 nanoparticles on the durability of concrete has been determined. Experiments were carried out to study water tightness, frost resistance, water absorption, and power parameters of concrete (stress intensity factors). It has been established that the introduction of nanoparticles into concrete improves the microstructure of its cement matrix, which leads to a decrease in the penetration of chloride ions into concrete and to an increase in its water permeability.
